Salvia plant named &#39;ib304-2 purple&#39;

ABSTRACT

A new and distinct Salvia cultivar named ‘IB304-2 PURPLE’ is disclosed, characterized by a dense, bushy plant habit, strong peduncles, medium purple-violet colored flowers. Flowers have a calyx flushed with dark anthocyanin. The new variety is a Salvia, normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Salvia hybrida.

Variety denomination: ‘IB304-2 PURPLE’.

BACKGROUND OF THE INVENTION

The new Salvia cultivar is a product of a planned breeding program conducted by the inventor, Steve Eggleton, in Wonga Park, Victoria, Australia. The objective of the breeding program was to produce new Salvia varieties with denser plant habits, strong garden performance, in a range of flower colors. The crossing resulting in this new variety was made during February of 2012.

The parent variety is Salvia hybrida ‘Eggben006’, unpatented. The pollen parent parent is Salvia ‘Ultra Violet’, U.S. Plant Pat. No. 21,411. The new variety was identified as a potentially interesting selection in February 2013 at a research greenhouse in Wonga Park, Australia. The breeder propagated and made further observations regarding stability and quality of the new variety, making the final selection in April of 2014.

Asexual reproduction of the new cultivar ‘IB304-2 PURPLE’ by vegetative cuttings was first performed during February 2013, at a research greenhouse in Wonga Park, Australia. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type on most than six successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘IB304-2 PURPLE’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘IB304-2 PURPLE’ These characteristics in combination distinguish ‘IB304-2 PURPLE’ as a new and distinct Salvia cultivar:

-   -   1. Bushy plant habit.     -   2. Deep Purple-Violet flower color.     -   3. Sturdy inflorescence.     -   4. Dense plant habit.     -   5. Dark anthocyanin coloration of calyx.

PARENT COMPARISON

Plants of the new cultivar ‘IB304-2 PURPLE’ are similar to plants of the seed parent, in most horticultural characteristics, however, plants of the new cultivar ‘IB304-2 PURPLE’ differ in the following:

-   -   1. Flower color of the new variety is purple-violet, flower         color of the seed parent is white.

Plants of the new cultivar ‘IB304-2 PURPLE’ are similar to plants of the pollen parent, in most horticultural characteristics, however, plants of the new cultivar ‘IB304-2 PURPLE’ differ in the following:

-   -   1. Flower color of the new variety is medium violet-purple,         flower color of the pollen parent is dark violet-purple.     -   2. Plant habit of the new variety is denser, with more branches         per plant.     -   3. Venation of the new variety is prominent, venation of the         pollen parent is very weak.     -   4. The central eye in flowers of the new variety is small, this         feature in the pollen variety is very weak or absent.

COMMERCIAL COMPARISON

Plants of the new cultivar can be compared to the commercial variety Salvia microphylla ‘So Cool Lilac’, unpatented. The two Salvia varieties are very similar in most horticultural characteristics, however, the new variety differs in the following;
